Answer 1

Answer:

20 m

Step-by-step explanation:

The width is half the length, and the perimeter is the sum of the lengths of all sides. We can write the equation of the perimeter as ...

... 60 m = L + L/2 + L + L/2

... 60 m = 3L . . . . . collect terms

... 20 m = L . . . . . . divide by 3

Answer 2

20 m L is the room twice as long as it’s wide .
